Why? What are you looking to gain? Move it in 3mm increments til you get the desired effect. Any more than that and the bike could become very unstable.

well here is the deal. i need to lower the back. getting a 2004 1000rr lower link to lower the back about 2 inches. when i ride by myself it is fine. when i want to ride with the wife i just dont feel confortable not being able to touch with both feet. i have nerve damage in one leg so that does not help. i know it is going to make the bike feel heavier but i would rather have that then drop the bike because i can't touch.

Ok, makes sense. I would try to keep the front adjustment as close to the rear adjustment as possible to maintain some sort of geometrical stability.

how far do you think i can lower the front without hitting the fairing stay. i have been looking at my bike and it looks like i would only be able to do about 1/2 inch in the front with the factory fairing stay. i did find online a harris fairing stay. don't know if it would clear the front forks enough though to lower to the desired amount.

I wouldn't worry about that. That's on the upper part of the bike.
The main issue is the front fender clearance for the underside of the upper cowl.
And quite possible the rear tire to the fender are of the subframe.

the farther you lower the front wont the forks stick out the top of the triples and in turn hit the fairing stay.

Well that's true. I'd say by the time you raise your forks to the lowermost mark, you'll be getting close to striking the cowl brace.

Of course, that also lowers the ground clearance, especially at the front.
I've seen bikes that were lowered for women riders, and they were scraping the lower cowls with suspension compression.

Always be careful and consider all aspects when lowering a bike quite a bit.
I understand your rationale, but still...be careful.
If minor changes can alter a bikes handling, imagine what radical changes in suspension geometry can do.

So you will compromise the overall handling & possibly even the safety of the bike while it is in motion just so you can stand flat footed when it is stopped - That's brilliant

LDH does have a good point.

*Please correct me if I'm wrong* with lowering the front it increses the chance of a "death wobble" "tank slaper" what ever you want to call it.

When I ride solo I tip toe too, or do the dirt bike ass slid off the seat thing. The added weight of a passanger is enough to compress the shock to the point I feel more sure footed.

I would go with droping the rear preload before moving the forks or adding a drop link. It may be enough.
